RESUMO
Objective:To investigate the effects of nutritional support on chemotherapeutic efficacy and safety in patients with acute myeloid leukemia.Methods:A total of 130 patients with acute myeloid leukemia who received treatment in Lishui Municipal Central Hospital from January 2021 to December 2021 were included in this study. They were divided into a control group and an observation group ( n = 65/group) according to different nutritional support methods. Patients in the control group were given routine intervention, while patients in the observation group were given nutritional support based on routine intervention. These two interventions were administered till 1 month after chemotherapy. Chemotherapeutic efficacy and safety were compared between the two groups. Results:Total response rate in the observation group was significantly higher than that in the control group [92.3% (60/65) vs. 78.5% (51/65), Z = 4.91, P < 0.05]. After chemotherapy, waist-to-hip ratio, arm girth, and body mass index in the observation group were (0.9 ± 0.1), (25.7 ± 1.2) cm, (21.9 ± 2.1) kg/m 2, respectively, which were significantly greater than (0.8 ± 0.1), (24.4 ± 1.1) cm, (20.6 ± 2.1) kg/m 2 in the control group, respectively ( t = 4.13, 6.63, 3.64, all P < 0.05). Transferrin, albumin, prealbumin, and total serum protein in the observation group were (1.4 ± 0.3) g/L, (27.5 ± 3.1) g/L, (171.3 ± 11.3) mg/L, and (61.2 ± 4.3) g/L, respectively, which were significantly higher than (1.3 ± 0.3) g/L, (25.2 ± 2.9) g/L, (154.3 ± 10.3) mg/L, (56.6 ± 4.0) g/L respectively in the control group ( t = 2.24, 4.48, 8.93, 6.31, all P < 0.05). The scores of emotional state, social status, role cognition, and somatic perception in the observation group were (57.5 ± 4.6) points, (64.5 ± 3.8) points, (56.5 ± 4.1) points, (62.0 ± 4.2) points, which were significantly higher than (47.9 ± 4.2) points, (56.4 ± 3.2) points, (47.7 ± 4.5) points, (55.5 ± 5.4) points in the control group ( t = 12.34, 13.04, 11.55, 7.65, all P < 0.05). The total incidence of adverse reactions in the observation group was 9.2% (6/65), which was significantly lower than 24.6% (16/65) in the control group ( χ2 = 4.43, P < 0.05). Conclusion:Nutritional support can substantially improve chemotherapeutic efficacy in the treatment of acute myeloid leukemia, decrease the incidence of adverse reactions, and is safe. Therefore, nutritional support for patients with acute myeloid leukemia deserves clinical promotion.
RESUMO
This paper discusses from two aspects of case writing and PBL implementation experience. PBL cases should be based on professional requirements and reflect professional characteristics. Health inspection and quarantine cases targeted at application-oriented talent cultivation can be integrated into relevant experimental skills items. At the same time, the forms of case writing are expanded according to the differences of theme forms, which are designed as parallel cases and serial cases, so as to be applicable to the curriculum integration in different areas. In the implementation of PBL teaching, students' learning status is the key to the efficiency of classroom discussion, which determines whether the implementation of PBL is completely autonomous learning or embedded instruction. Teachers should establish cooperative learning atmosphere to improve the efficiency of classroom discussion
